With them, you should be able to use a passive cooling without your ACPI BIOS support. But, it is not MFC'ed yet. You can try the following change: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/acpica/acpi_thermal.c.diff?r1=1.65;r2=1.66 You need to have some knowledge to set them correctly. Just for reference, my laptop has _TC1=0, _TC2=12, _TSP=40. Sincerely, -- Hajimu UMEMOTO @ Internet Mutual Aid Society Yokohama, Japan ume@mahoroba.org ume@{,jp.}FreeBSD.org http://www.imasy.org/~ume/
